## Constructing a Cylinder Feature

Construct Cylinder dialog box

Planner allows several methods for constructing a cylinder. The following table lists the various types of constructed cylinders, along with their necessary inputs. Some features may require no inputs while others may require six inputs or more. In the following table, the term "Any" indicates that the construction can take any type of feature as input for construction. Planner allows the features to be selected in any order.

CONSTRUCT FEATURE TYPE | SYMBOL IN EDIT WINDOW | # OF INPUT FEATS | FEAT #1: | FEAT #2: | COMMENTS
Auto Cylinder | - | - | - | - | See "Auto Cylinder Construction".
Best Fit Cylinder | BF | At least 6 inputs are needed. See Notes below. | - | - | Constructs a best fit cylinder using the given inputs.
Best Fit Recomp Cylinder | BFRE | At least 6 inputs are needed. (1 must be a point) See Notes below. | - | - | Constructs a best fit cylinder using the given inputs.
Cast Cylinder | CAST | 1 | Any | - | Constructs a cylinder at the centroid of the input feature.
Project Cylinder | PROJ | 1 or 2 | Any | Plane | One input feature will project the cylinder to the workplane.
Reverse Cylinder | REV | 1 | Cylinder, Cone, Line, Slot | - | Constructs a cylinder with a reversed vector.

You can construct Best Fit and Best Fit Recompensate Cylinders from two circles. The input circles must be of type Constructed Best Fit (BF) / Best Fit Recompensate (BFRE) or Measured circles. The total amount of hits in each circle must be at least three.

For Best Fit (BF) or Best Fit Recompensate (BFRE) constructions, while you can use any feature type for your input features, BF and BFRE fit types are typically used with point features or point sets (a scan of points, a feature set with points, or an expression that resolves to an array of points).

If you select inappropriate feature types, Planner displays "Cannot construct [feature]. Combination of input features not accepted." on the status bar.

To construct a cylinder:

1. Access the Construct Cylinder dialog box (Insert | Feature | Constructed | Cylinder).

2. Input the desired features.

3. Select the method of construction. Available options include:

- Best Fit or Best Fit Recompensate Cylinder

- Cast Cylinder

- Projected Cylinder

- Reversed direction Cylinder

- Auto Cylinder

4. Click the Create button.

When two or more features are involved, Planner automatically determines the necessary order of the input features. This improves the accuracy of the measurement process.
